Below are some pics of the assembly of my first DSI table!

The first pic shows the only visible cable (power to outlet) when the top is closed for use.  Some unplanned modifications were later needed to get the best performance and picture. The second picture is the beginning of where the projector is mounted. This was originally supposed to be placed inside with a front surface mirror.  It did not work out so well. I think the main issue was I was trying to go beyond the capabilities of the projector. The keystone setting was not able to go as far as I needed even with different positions. This severely effected picture quality anyway. Without the mirror and with the projector facing directly at the acrylic I was able to get the best picture quality.  The next few pictures are showing the ventilation for 120mm fans and the inside of the table.  Later on I added legs due to placement of the projector. I also later on lowered the camera to get better blobs. I thought why not since I did the same with the projector and I did not want to spend a lot of money on a new camera lens.  The last picture shows the cabinet opened with two supports holding it up. I made this so I could work inside it easily. There is also an external power button to power to turn everything on. It is wired to the computer switch. Using a smart strip I am able to power the projector and IR LEDs on automatically.

Here is my CCV 1.3 config. It seems to work perfectly for me when it’s configured this way.

Congrats to your 1st table. Are the framerate of 30fps and the full turned on amplify correct? Would be nice to see a little video of it smile
